Abstract Scope Coherent diffraction imaging (CDI) with X-ray energies greater than 50 keV opens up new opportunities for nano-scale resolution of crystal strain and defects in macroscopic volumes. We describe experimental and computational advances in this direction, which include signal processing innovations to contend with reciprocal space scaling, and partial coherence corrections. We also present proof-of-concept imaging results of gold nanoparticles with synchrotron X-rays at 52 keV energy, substantially higher than the energies employed in present-day coherent X-ray scattering measurements. Our methods are poised to make timely use of the upgraded coherence capabilities of next-generation X-ray sources over the next few years. We anticipate extending this high-resolution strain field imaging capability to hitherto difficultto- access environments, such as crystals in dense catalytic media or embedded grains in a polycrystalline bulk. This ability could benefit a vast cross-section of materials research, like structural and functional materials design, and validation of materials physics models.
